As Tom said. There's a lot more info on what's needed then "LB7" and "wiring diagram.
One, there is two electrical versions depending on which year LB7 you are using
Two, the electrical schematics for the "LB7" are Several hundred pages so you are not going to get anyone to just "post" up the diagrams. You need to be very specific or download them from GMupfitter as already mentioned
